a) if x= -10^4 then log 10 = -4

b)if x= 2^8 then log 2x = 8

c) log2 2= 4

d) if x= 3 then log10 3=x

e) log 10 256-2log 10 a/log 10 b

f)log 10 (a-b)= log 10 a/log 10 b

g) the gradient of the graph of y= 2x^x at x= 2 is 2e^e

h) the gradient of the graph of y= e^x at x= 2is 2e

can you explain why? I dont get this

which three statements are true?

a) if x= -10^4 then log 10 = -4

b)if x= 2^8 then log 2x = 8

c) log2 2= 4

d) if x= 3 then log10 3=x

e) log 10 256-2log 10 a/log 10 b

f)log 10 (a-b)= log 10 a/log 10 b

g) the gradient of the graph of y= 2x^x at x= 2 is 2e^e

h) the gradient of the graph of y= e^x at x= 2is 2e

a, b
